  • Title: [Results of the long laboratory storage of Streptoverticillium hachijoense (Jamaguchi) Baldacci, the producer of trichomycin].
    Author: Konev IuE, Kuz'mina ED.
    Journal: Antibiotiki; 1975 Mar; 20(3):235-9. PubMed ID: 1169905.
    Abstract:
    Viability, morphologo-cultural features and antibiotic properties of Sv. hachijoense, strain LIA-0052 stored for 10 years in a dry state and in the state of a resting culture were studied. Spores and mycelium of 2-week strains most stable to some chemical and physical factors were used for drying. It was found that viability of strain LIA-0052 was maintained for a longer period of time after lyophilization, in garden soil and agar culture under a layer of mineral oil. By the end of the observation period the viability of the soil culture decreased and the morphologo-cultural properties were stabilized. When the strain was cultivated on media with sucrose, the level of its antibiotic activity increased.
